COMPARE is an acronym given to a traffic congestion management program that has been formulated through the cooperative efforts of all the major Cities and Transportation Agencies in the Hampton Roads region of the Commonwealth of Virginia. This regional effort encompasses a balanced marriage between Intelligent Vehicle Highway Systems (IVHS) technologies and Transportation Demand Management (TDM) techniques towards managing traffic congestion in an urbanized area. COMPARE stands for Congestion Management Plan: A Regional Effort. The basic premise of the plan is to provide a multi-modal and integrated transportation system that allows the traveller or motorist to better compare alternative routes or modes of travel that are available, when selecting the optimum route of travel. The COMPARE program can function as a blue print to assist Metropolitan Planning Organizations and State DOTs in formulating regional congestion management systems (CMS), as required by the ISTEA legislature, for the purpose of enhancing the performance of the transportation system.
